MOUNTING FOR RELAYS OR THE LIKE.

Specification. of Letters Patent.

Patented Aug. 24, 1915.

Application filed May 10, 1915. Serial No. 27,193.

To all H'imm it muy concern Be it known that I, EUGENE A. REIXIIGE, a citizen of the ljnited States, residing at Rochester. in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Mountings or Relays or the like, of which the fol- Jwing is a full, clear. concise, and eXact description. ret'erence being had to the accompanying drawings, forming a part of this specification.

The present invention relates to mounting for relays or the like. here a large number of similar individual pieces of apparatus, such as telephone relays are to be mount.- ed and housed. it is imperative that these units be arranged in such position that inspection and repairs can readily be accomplished without danger of getting other units or pieces of apparatus out of order. The inaccessibility of relays as heretofore mounted on relay racks or boards renders them not only difiicult of inspection but renders adjacent units liable to damage during the repair of any particular unit. This inaccessibility also has a tendency to cause neglect of inspection and even of repair.

The object of the present invention is to provide improved mounting means for relays or the like so as to render accessible any desired unit or units from a board or rack, and to allow closer mounting of the units.

In the accompanying drawings I have illustrated one embodiment of my invention. It is understood, however, that the present invention is not limited to mounting solely for relays but may be applied to other forms of apparatus, such as heat coils, lightningarresters, resistance coils,

or any similar or analogous articles or uses.

Figure 1 is a plan view of a bank 0t relays, provided with my improved mounting means. Fig. 2 is a side elevation of a pair ofrelay banks, and Fig. 3 is a fragmentary detail view illustrating the manner in which the movement of the cross bar or mounting bar is secured.

It is customary to provide frames in which the relays or. similar apparatus are mounted. I have shown a frame as consisting of adjacent I-beams 1 and 2- and it is to be understood that these beams may be. arranged vertically or may be arranged horizontally. Cables 3 and 4: containing wires which are connected tothe relays 5 are disposed in the hollow space between the flanges ot' the beams or bars 1 and 2. In stead of employing an I-beam, channel bars or other structural shapes may be employed.

The relays 5 which may be or any preferred form. but which in the present drawng are of the type disclosed in my co-pend- 111g application Serial No. 27,192 filed May 10, 1915, are mounted upon a cross bar 6 having the sleeves 7 secured thereto. The sleeves T are slidably mounted upon guide rods 8 supported from the beams 1 and 2 by means of the angle brackets 9. The guide rod 8 (see Fig. 3) is preferably secured to the angle brackets 9 by means of a. shoulder and a stud 10 passing through one part of the bracket and secured thereto by means of a nut 11. The sleeve 7 is rigidly secured to the cross bar (3 as by threading or expansion therein and serves to hold the cross bar 3 in proper relation to prevent tilting of the bank 0t relays. As shown in the present illustration the cable -.t has its wires connected to the windings of the relays 5 by means of the terminals 12 which are secured to the rear insulating heads of the windings and pass through insulating bushings 13 in the cross bar 6. The cable 2 is tanned-out in the well known manner, but is provided with a goose-neck bend as shown in Figs. 1 and 2 so as to allow bodily movement, without imposing any particular strain upon the individual wires leading to the terminals 12. In a similar manner the cable 3 which is fanned-out to make connection with the terminals 15 leading to the contact springs of the relays is provided with a goose-neck so as to allow a movement of the strip of relays. In this manner the pull upon the cr oss bar 6 is equalized from both cables and there is no tendency whatsoever to bind the sleeves 7 upon the guide 8. Each individual relay is secured to one of the cross bars 6 by means of a stud 16 and a nut 17 which secure the cores of the relays to the bar 6 in a permanent manner.

.above andbelow the particular row are pushed forward leaving the particular row inaccessible condition. It can be seen that this mounting not only furnishes greater facilit1es for inspection and repair but it alsoallows the relays to be mounted' closer to eachother than has heretofore been pos sible; thus effectinga great saving of valuable-space.

his to be understood that this invention applies not only to the mounting of relays in the particular mannershown, but that the construction may be such that instead of having the relays pullforward out of the bank they'may be pulled backward out of the bank'fo-r the purpose. of inspection, re-

pair and replacement.

I do not intend to be limited to the precise details f construction illustratedas it is obvious that modifications will at once be apparent to those skilled in the art. Such modifications I consider to come'within the scope of my invention.

' \Vhat ,I claim as new and desire to secure by'Letters Patent is the following 1. In combination, a pair-of supporting beams, guides mounted on said beams, 'a cross bar mounted upon said guides and having a limited motion thereupon and means for mounting a plurality of similar units on said cross bar. 2. A frame comprising substantially parallel supporting beams, brackets having guides, said brackets being attached to said 'beams and having the guides extending in parallel relation to each other, a cross bar slidably mounted on'said' guides, relays mounted on said cross bar and. cables adjacent said beams, said cables being connected to said relays and having limited movement to allow'bodily movement of the cross bar and relays.

3. In combination, a pair of substantially parallel supporting beams, brackets mounted on said beams, rods mounted on said brackr ets, said rods being substantially parallel to each other, a cross bar having a sleeve slidably mounted on each rod, said cross bar having a limited range of movement between said brackets and the ends of said rods.

' i. A frame comprismg a pair of beams, brackets secured to said beams, parallel each bracket, a slide mounted on each guide,

a cross bar connected to said slide, relays mounted on said cross bar, cables for said relays, said cables being supported in said channel beams and having loops for allow ing bodily movement of said'cross bar.

6. A pair of beams, a pair of parallel guides,'one on each beam, a cross-bar slidable on said guides, relays mounted 011 said cross bar and a cable connected to said relays.

In witness whereof, I hereunto subscribe my name this 1st day, of May A. D. 1915.
